Hey, noob here. So far reading some threads I like what I see! I hope that I can get a little help or advice also. Heres my situation, I have a 91 hatch, pretty much to sum it up I bought it with a motor only swap, and would like to carry it out. I am a believer in the Y5 and the head it provides, so thats why I would like to the whole swap. First and foremost, its obviously got the stock ecu, harness, and i/m, which means stock fuel and air parts. I would like to use the y5 i/m and fuel parts. Do I need or would it be helpful to do the p2n and harness from the y5? I would also like to not have to power up the vtec with damned button and have the ecu do the work, so would the p2n also help me out there? I will start with this and see if you guys can help me out, thanks!
